Let's talk NERVO. The Aussie-born sisters — Miriam and Olivia — are one of our fave musical duos (listen to their latest club banger right hurr), and they've been out 'n' about this New York Fashion Week. Natch, the megababes are killin' it in the fashun department (they're a must-follow on the 'gram), and we're stoked they agreed to do an exclusive photo diary with us. Scroll to see how NERVO took on NYFW (FYI: Paris Hilton and breakfast cupcakes are involved).
